10fClaims): (Cr m -32y This invention relates to imp movements' iriivallv structures and particularly to th'e'method of ap plying facing elements or boards in the con,-

struction of walls or buildings. The method may 5 be applied in relation to studdings o'r'to the floorf ing stringers and facings that are ordinarily'covg,

ered with plaster, cement or stucco, The invert tion also includes means for assisting in bonding plaster and the like: to the board. as wellas. to 10 assist re-enforcing and locking the joint.

Patents 1,998,610 and 2,003,755.

Features of the invention include; the .wall structure; the use of fibrous" slabs or the like in forming such structure; the bonding andfreenforcing elements or devices; the specific arrangement of the board or slabs to form the wall or the like; their proportionate lengths and'widths' in relation to the spacing distance between studding; the'arrangement'of the vertical'jointsfon the studding; andgenerally, all details of'construction of re-en'for'cing element, and meansfor connecting it to the boards. e I ther and additional objects, of the invention ing which form a part of the application;

purposejthe opposite end of each slab l.l,-iscut out to provide a recessor notch at opposite longitudinal, edges. There is no intention to limit the shape of the longitudinal elements, just so they are formedto provide over-lapped, and/or inter-locked joints which give the greatest insue l lating value at thejoint. This application is an improvement on my previously stated to increase the; bonding of the plasterialong the joint and at the same time reenforceandlock the joint.

this invention there is a reduction of the tendency ofplas'ter to crack along the joint as. the re-enforcing .means requires the plaster to be, sufficiently thick to cover thein and thusmake it im-- 20 In Figure v 2 'the .'plaster receiving base H, has secured thereto joint locking elements which are possible to skin the-plaster.

providedwith staple .-l4 which preventsthe tend.- ency offlock' l5, to swing. The joint locking means maylbeof thetype shown in Figure 6 but it is to beunderstood that the application is not limited to such construction but relates to a means for locking the joint andv assisting in bonding the plaster. As long as the joint locking means efficiently locks the joint, the points of contact with the plaster surface may be at the outer endsof the elements.

In Figure 3 is shown a modified form of overlapping joint 26,which, may be used if desired. The element I5, is secured to the board ll; by means of spikes l8, and the element'l5 is prevented, from swinging by means of staple H,

which is adaptedto have the endfll," bend on the lower or under side of the board I l.. The element l5, contacts the board by portions |1',. |a and I9 but itIneed not. contact the board atlmore than two points, The plaster fills the spaces 22, be-,

tween the element l5 and the board ll, thus insuring proper plaster bondingand in addition V insures .a proper thickness of. plaster over the whole-plasterbase. It is preferred that the stap1e-H,. be placed'in thev depression 23, thus in-' suring that the staplewill not be displaced.

It is :to be -unde1 stood'that if a re-enforcing 50 l and bonding element in the general shape as It isan important, object of this, invention s When wallsare constructed in accordance with shown in Figure 4 of "my 'Patent 1,998,610 of August 23, 1935 isused, the staple I4, is not required.

For the purpose of this application there has been set forth certain structures and certain methods of using the same but itis to be understood that they are here presented for illustrative purposes only and are not to be accorded any interpretation such as might have the effect of limiting what is claimed as the invention short of its true and comprehensive scope in the art.

I claim:

1. In combination with studding, slabs of material secured to and bridging the studding and formed to provide an overlapped joint which extends transversely of the studding, a plurality of plaster bonding and reenforcing structures each attached to one of two contiguous slabs and extending across the corresponding lapped joint and engaging the surface of each slab at spaced apart points whereby the major portions of said structures are held in spaced apart relation to the surface of the slabs, each of said looped structures having prongs which are driven into one slab, and a staple securing the looped structure to that same slab at a point between the prongs and the j oint; I

2. A plaster-receiving base of fiber composition composed of aplurality of slabs formed and laid to provide an overlapped joint which can be opened by pressure applied against one face, and plural means arranged across the joint to assist in bonding plaster and to prevent opening as the result of applied pressure, each means having two spaced arms, each arm having projecting portions to engage the surfaces of each board and each arm havinga prong driven into one and the same slab whereby the arms are spaced from the surface of the slabs to permit plaster to enter between the slabssurface and the arms.

3. A plaster-receiving base of fiber composition composed of a plurality of slabs formed and laid to provide an overlapped joint which can be opened by premure appliedagainstone face, and plural means arranged across the joint to prevent opening as the result of such applied pressure, and to assist in bonding plaster, each means having two spaced arms the major part of the arms 40 spaced from the surface of the slabs, and each arm haying a prong driven into one and the same slab and each arm provided with means extending from'each arm to engage the surface of each board, and means to prevent swinging of each of plural means about the prongs as a center, anti-swinging means being arranged be tween the prongs and the joint and being attached to the slab into which the prongs are driven. I

4. A plaster receiving base of fiber composition composed of a plurality; of elements laid in substantiallycoplanar'relationto form a joint, and

so that the elements can be pressed from coplanar relation with one another during application of plaster to'one surface, and means arranged across the joint, and lying spaced apart and substantially parallel to'one side of the plaster-receiving base, and contacting'the base'at spaced apart points whereby the major portion of the means is spaced from the face of the base,

and attached'to one of the slabs acting to prevent the movement of one of the slabs to a noncoplanarrelation with the other as the result of applied premure.

5 5. A wall structure including studding, slabs of material secured to and bridging the studding and provided with overlapped joints which exthe plaster receiving surface, thus preventing opening ofthe joints when plastering pressure is applied against the faces of the slabs in a direction toward and at points between the studdings and to aid in bonding the plaster.

6. In a wall, moisture absorbable, plaster-receiving base composed of a plurality of fibrous slabs provided with a longitudinal overlapped joint and rigid means on one face of the slab extending substantially parallel to the face, and contacting the face only at spaced apart points whereby the major portion of the means is spaced from the faces of the slabs, extending across the joint to aid in bonding the plaster and prevent opening of the joint as the result of applied pressure. 7

'7. A plaster receiving base'composed of a plurality of expansible slabs of composition fiber provided with overlapped edges forming an air tight joint, and'means of substantial width extending across the joint andengaging the faces of the slabs only at spaced apart points to hold the major portion of the means spaced from the surface of the slabs and to aid bonding the plaster and to prevent opening of the joint and introduction of plaster therein as the'result of such ap-' plied pressure. I I

8; An article of manufacture comprising a sheet of composition board capable of acting as a plaster receiving base and provided with a tongue on one edge and a depression on the oppo-' site edge to cooperate with a like sheet to form an overlapped joint, and means attached to one face of the sheet adjacent one edge and extending outwardly therebeyond, said means contacting the face of the sheet only at spaced apart points whereby the major portion of the means is held spaced from the'surface of the sheets.

9. A wall structure including studding and sheets of plaster base material secured to and bridging the studding, and providing an overlapping joint capableof being opened by applied ped joint, and rigid means attached to one face,

adjacentone edge,and extending outwardly therebeyond, said means extending substantially parallel to the face and having projecting portions for contacting the face at spaced apart points whereby the major portion of the means is held spaced from the surface of the board.
